Climate change has hit the Arcticworse than ever over the past few years, but that doesn't mean the Northern Hemisphere will be experiencing a mild winter this year.
In fact, a new study shows that the polar vortex is shifting, and it will make winters in the US East Coast and parts of Europe even longer, with exceptionally cold temperatures expected during March.
The polar vortex is that lovely zone of cold air that swirls around the Arctic during winter. When parts of the vortex break apart and splinter off, it can cause unseasonably cold conditions in late winter and early spring in the Northern Hemisphere.
This happened in early 2014 and caused an extreme-weather event in the northern US and Canada.
